Is it possible in nginx to have a location {...} block that matches query parameters. For example I want to pick up that preview=true in URL below and then instruct it to do several different things, all possible in a location block.

The problem I'm having is that my test stuff doesn't seem to match, it seems like I can only match the URL itself?


location ~ ^(.*)(preview)(.*)$

Or something aloong those lines?

What are you trying to do? – Michael Hampton Oct 12 '12 at 13:07
To match preview=true in the url in order to disable caching in the location (as location / caches) – Dave Oct 12 '12 at 20:02

Use the proxy_cache_bypass directive.

proxy_cache_bypass $arg_preview;

This is correct; thanks Michael. Unfortunately it's not possible to match arguments in a location {} block though – Dave Oct 13 '12 at 10:27
You shouldn't be using a separate location block at all. If this doesn't work with your existing directives, you've probably found a bug in nginx. – Michael Hampton Oct 13 '12 at 12:28
